S!
Swiss, if IL-2 has worked with 10.8 and 10.9 I see no reason to bash ATI/AMD. If that driver set works why uograde to next one, if it works well on other titles you play as well

That we even got the drivers to work in the first place is kind of a feature in itself as IL-2 is over 10 years old and not really one of the hottest releases around. Now with a working driver set why complain? NV has it's problems as well, just check some forums
Also remember IL-2 uses a jurassic version of OpenGL and from the start IL-2 was optimized to NV due various reason I won't go into here. Say IL-2 was coded in latest OGL I am sure there would be far less glitches. NV or ATI, both work and deliver performance that fill the needs of a gamer. Not everyone plays these damn shooters pouring in from doors and windows. For me ATI 5870HD and nVidia 480GTX have worked as advertised
